Don't know if this is just firmware or would require hadware updates:
The mmm has an onboard temp.monitor to protect from overheating? It would be nice to be able to plug the mmm into an eagletree data logger or the dx3s receiver (maybe via servo y cable) to be able to monitor/review temps. Same thing goes for reading rpm's.

These things can already be done with the datalogger/dx3s, but it would somehow simplify setting up for temp&rpm.monitoring.
